Same for Florisboard: press ?123
, then 1234
.
Side note: Florisboard also allows you to use custom keyboard layouts, which would make it possible to
a) make the numbers keypad accessible with one click from the main layer and b) move the numbers actually to the right side (not in the middle like they’re now).
There’s a catch though: currently, the process is quite technical. An easier way is planned, but it’s hard to say when it will arrive.
I use dict.cc because they support the context menu action to look up definitions.
